Just write your own inside() function. I gave it a go with the following, and it
seems to work pretty well. It should really be improved with the equivalent of
an inside_vector, so you can usefully use it with open meshes, but it's OK for
a quick attempt.

#macro inside_m( obj, pos )
 #local current = pos;
 #local dir = x;
 #local done = 0;
 #local num = 0;
 #while ( done != 1 )
  #local norm = <0,0,0>;
  #local inter = trace( obj, current, dir, norm );
  #if ( vlength( norm ) != 0 )
   #local num = num + 1;
   #local current = inter + <0.0001,0,0>;
  #else
   #local done = 1;
  #end
 #end
 (mod( num, 2 ) = 1)
#end

Cheers,
Edouard.
